JHipster release 4.5.4

What’s new

This release has many minor bugs corrected, and some libraries upgrades.

It was triggered because of a https://npms.io/ outage, and this service is used by our marketplace (so it caused errors when using the marketplace).

This issue is tracked by #5934 but we had many duplicates. As a related note, we had a big increase this week in GitHub tickets not following our guidelines: if you need help, please read those guidelines, and don’t make the whole team lose time.
